Master List From Twelve Tables

Hello,

I am putting together a database for a charity and am having some problems. At present I am working seven days a week and my time for research is so limited that I can only ask here for advice since I have neither the time nor resources to seek it out myself.

We do mail shots to various trusts and businesses to appeal for donations. At present we have two large, bloated MS Works Databases (one for Trusts and one for businesses) that contain names, addresses and so on. I have taken on the task to make our mail shoots more efficient. My vision is that the majority of time should be spent searching out new business/trusts and organising events while actually doing the mail shoots should basically be done at the touch of a button (it won't quite work like that, but previously the actual mailshots took up about 80% of the time. I want to drive that number down)

Having no Access experiance whatsoever I set about creating a Database with twelve tables, one for each month. Each month would contain a list of places that we would "hit"

I then came across a problem. When I am searching out new addresses I would have to cross reference them on 12 different tables. This struck me as being impractical but at the time of creation I didn't have the foresight to create a masterlist. Although I do have the list on my Works DB, it would be useless as time passed since no more entries would be inputted on there.

I was hoping someone could tell me how I can put together a masterlist using the data I already have and maybe if possible setup the 12 tables in such a way that by inputting an entry on one of them will automatically crossover the name of the business to the masterlist without me having to enter it twice.

I realise this may sound confusing, and if i had more time I would research the answer myself but I am stretched to the limit and know too little about this application. I did try to take on a Lyndia (sp?) course but again I just don't have the time. If you have any questions, I will check back later to answer them.

I am using Access 2002 (but my DB is in Access 2000 format - so it says)

Thanks kindly.
